I need new inlet plenum gaskets on T/body, plenum cover and possibly head, is there a way of making these replacements fit and forget, so they dont leak and will last a while?

 

use a cometic gasket on the inlet to head and take apart the plenum and take off the throttle body clean all the old gasket off and get some sealant called TIGER SEAL and put this on both sides of the plenum and bolt it together with no gasket just tiger seal on both surfaces and it wont leak again i have done this many of times and it hasnt failed yet

 

it did on mine at 32psi

again and again and again

oh and its off again at the mo

its a swedish style one though

 

there was a thread about this about a month back, cant remember what the title was though

 

You could get them 'o' ringed...

 

my cometic ones are fine on mine.. with the plenum one i drilled through the threads and bolted right though bolts and lock nuts... has been ok so far..

 

i also had the plenum skimmed as it werent perfectly flat...

 

With the paper and cometic gaskets the key is to bolt through as gibbo says. Otherwise the plenum to inlet manifold bolts "pinch" or "bind-up" and you dont get the full clampimg force throughout the mating surfaces.

 

Really Mark? How come?
